PREVENTIC Collar - 18"
The Preventic Collar, containing 9.0% Amitraz, prevents ticks from attaching to dogs and detaches existing ticks within 48 hours. Activity starts within 24 hours and will last up to 3 months. Normal wetting of dog by rainfall does not reduce effectiveness; however, remove collar before bathing. On thick coated dogs you should clip the neck so the collar maintains skin contact. Cut off and dispose of excess. Not effective against fleas.
